区域电离层模型在大洋洲的适用性分析

Applicability Analysis of the Regional Ionospheric Model in Oceania

为验证区域电离层模型在大洋洲的适用性,利用达尔文和珀斯站点的电离层探测数据,对亚洲和大洋洲地区模型(Asia-Oceania Model, AOM)在大洋洲的预测结果进行了统计分析,结果显示:两个站点中foF2和M3000F2的观测统计值与模型预测值变化趋势有较好的一致性;foF2模型值与观测值的全年均方误差分别为0.99 MHz和0.62 MHz,相对误差分别为11.82%和8.59%;M3000F2模型值与观测值的全年均方误差分别为0.09 MHz和0.08 MHz,相对误差分别为3.12%和2.54%;在此基础上,分析了预测偏差的日统计、季节统计和全年统计变化规律。上述研究可为区域电离层模型研究及新模型的建立提供参考价值。

To verify the applicability of the regional ionospheric model in Oceania, the prediction results of the Asia-Oceania model(AOM) are statistically analyzed by the ionospheric sounding data of Darwin and Perth. The Statistical result shows that: The observed statistical values of foF2 and M3000 F2 at the two sites are consistent with the trend of the model predicted values. The RMSE of foF2 in Darwin and Perth is 0.99 MHz and 0.62 MHz, respectively, and the RRMSE is 11.82% and 8.59%, respectively. The RMSE of M3000 F2 in the two sounding stations is 0.09 MHz and 0.08 MHz, respectively, and the RRMSE is 3.12% and 2.54%, respectively. The various rules of the diurnal, seasonal, and latitudinal characters of prediction deviation are analyzed on this basis. The above research provides a reference for regional ionospheric model research and the establishment of new models.
